1.She diagnosed Liver Qi stagnation and sent Harvey to a Shen balancer.

安妮特：她诊断出肝气停滞，把哈维送到了沈平衡器。机翻

2.This determines how the load balancer distributes incoming requests to the backend servers.

这决定了均衡器如何将传入请求分发到后端服务器。机翻

3.So load balancers can operate at different layers.

因此, 均衡器可以在不同层上运。机翻

4.Second is the layer in the OSI model that the load balancer operates at.

个是均衡器在 OSI 模型运层。机翻

5.All right, but what are our load balancers distributing traffic to?

好吧, 但是我们均衡器将流量分配给什么?机翻

6.Now, when we talk about load balancers, there are two relevant points of discussion that are worth bringing up in your interview.

现在，当我们谈论均衡器时，有两个相关讨论点值得在面试提出。机翻

7.Our load balancer will then take that request and send it to our API gateway.

然后，我们均衡器将接收该请求并将其发送到我们 API 网关。机翻

8.From here, requests sent from the client hit our load balancer.

从这里开始, 客户端发送请求会触及我们均衡器。机翻

9.And then our load balancer is going to be a layer 7 load balancer.

然后, 我们均衡器将是一个 7 层均衡器。机翻

10.Load balancers distribute incoming traffic across multiple servers, and they're key to scalability in just about every single system design interview that you're going to do.

均衡器在多个服务器之间分配传入流量，在您将要进几乎每个系统设计面试，它们都是可扩展性关键。机翻

11.Now, the API gateway's responsibility is to take the incoming requests from the load balancer and forward them on to the appropriate service.

现在，API Gateway 职责是接收来自均衡器传入请求，并将其转发到相应服务。机翻

12.Layer 7 load balancers are interesting because they can make routing decisions based on the actual content of the request, such as the URL or the header.

7 层均衡器很有趣，因为它们可以根据请求实际内容（例如 URL 或标头）做出路由决策。机翻

13.It's worth mentioning that these three components, the client, the load balancer, and the API gateway, are going to be present in roughly 90% of the system design interviews that you do.

值得一提是，这三个组件（客户端、均衡器和 API 网关）将出现在您所做大约 90% 系统设计面试。机翻
